VENTILATED WATER-CLOSET.

SPECIFICATION forming part of Letters Patent No. 470,740, dated March 15, 1892.

Application filed June 24, 1891. Serial No. 397,308. (No model.)

To all whom it may concern:

Be it known that I, CHARLES A. BLUHM, a citizen of the United States, residing in Michigan City, in the county of La Porte and. State of Indiana, have invented a new and useful Improvement in Ventilated Water-Closets, of which the following is a specification.

My invention relates to water-closets.

'lhe object of my invention is to provide a closet with means for Ventilating the same and conveying away gases, fumes, or odors 'line' 2 2 of Fig. 1.

which tend to arise when the closet is in use,

and whereby at the Sallie time the person of the occupant will not be subjected to disagreeable drafts, to the end that all odors and fumes may be prevented from escaping into the room.

My invention consists, in combination with the closet-bowl, of a seat furnished with a holtow chamber or passage having openings through its bottom communicating with the bowl and connected with an air-escape or eX- haust iiue or pipe, whereby the fumesand gases in the bowl may escape.

It' also consists, in connection with such hollow seat, bowl, and air-escape pipe or fine, in furnishing the hollow seat with an air-inlet passage to admit free air to the bowl and cause an air-circulation through the same and through the hollow seat, and at the Sametime protecting the person of the occupant from disagreeable drafts.

It also consists in the novel devices and ynovel combination of parts and devices herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, which formy a part of this specitcation, and in which similar letters of reference indicate like parts, Figure 1 is a central vertical sectional view of a device embodying my invention. Fig. 2 is a plan or sectional View, looking from the Fig. 3 is a vertical section on the line 3 3 of Fig. 1, and Fig. 4 is a detail view of the valve.

In the drawings, A represents a closet-bowl, which may be of any Well-known or suitable construction.

B is the closet-scat, hinged in the usual manner to the stationary frame C, .that is 5o supported on the bracket I).

E is the hinged cover of the seat.

The seat Bis furnished with a hollow chamber or passage b, preferably extending entirely around the seat-rim, which overhangs the rim or lip a of thev bowl A'. Leading through the bottom wall of the hollow seat are air passages or openings Z1', which communicate with the interior of the bowl, and one or more' air passages or openings b2 lead from the outside of the bowl into the annular chamber b to admit the fresh air into the same and thence into the bowl,'as indicated by the arrows in Fig. 1. sage Z) in the hollow seat communicates at the rear or hinged end of the seat with a similar lating pipe or flueF. An intermediate ornamental box or chamber G may preferably bc interposed between the pipe or flue F and the stationary part or frame C.

To make a close or tight connection between the hinged hollow seat and the bowl A, I provide the former with a rubbergasket or ring b3. `The annular chamber or passage b in the hollow seat I likewise preferably prof vide with valves b4 b4. When these valves are closed, the air admitted at the inlet-port b2 will be forced down through the openings b at the front portion of the seat into the bowl, and will thence pass out through the openings b at the rear portion ofthe seat. lVhen the valves b4 are open, the air, passing into the hollow seat at b2,'n1ay pass directly through the hollow seat or rim and out through the exhaust-pipe F without passingthrough the bowl. In this latter case the current of air through the hollow seat will, however, by its exhaust action draw the air and gases from the bowl into the hollow seat, and thence out. The Ventilating-'pipe F may communicate with the smoke or, other flue of the building or may be carried directly out through the roof. When the hinged cover E The chamber or pasis down or closed, there is a continuous airpassage for the ventilation of the bowl in through the inlet-port b2, through the hollow chamber l) of the seat-openings b', into the bowl, and out through the openings b at the rear of the seat-passages b c, through the ventilating-ppe F.

I claim- 1. The combination, with closet-bow1 A, of hollow hinged scat B, having openings com: lnunicating with said bowl, hollow frame U, to which said seat is hinged, the air-passage in said frame communicating with the airpassage in said seat when the latter is down, and a Ventilating-pipe F, communicating with said hollow frame, substantially as specified.

2. The combination of.i closetbowl A with hinged seat B, having chamber b and openings b and b2, the former communicating with the interior of -the bowl and the latter outside of the same, and a Ventilating pipe or line communicating with said chamber l1, substantially as specified.

3. The combination of closet-bowl A with hinged scat l, having chamber b and openings b and b2, the former communicating with the interior of the bowl and the latter outside hollow hinged seat B, having chamber' b ex` tending around Ithe same and furnished with openings b', leading into the bowl, and airinlet passages b2, leading-outside of the bowl, frame C, having hollow chamber or airpassage communicating with said chamber or passage b, ventilating-ue F, communicating with said air-passage b c, hinged cover E, and a box or chamber G, interposed between said Ventilating-flue F and said frame C, substantially as specified.
